They are an ellipsoid shield. So basically they measure a 6.75 base curve horizontally. However, from top to bottom in the vertical direction they measure 4. Not the best donor for many cuts, but if you score them cheap enough they can be fun to play with. Might make some decent XX X-Metal cuts. For those who don't mind the flatter base curve. May touch some eye lashes with people that have less nose bridge, or are of Asian descent.i have the chance to get a bundle Enduring lenses - but don't have an idea which base they have.....
maybe some member could let me know?!?
thanx
